I don't understand what this means. How can you use the oilpan without connecting it to APM??

"after have been facing a loiter mode issue, i ve discovered that even the blue light on the gps is solid, the red light on oil pan still flash, unless i connect it to the apm."

Do you mean that you have the GPS connected to the oilpan? DO NOT do this. It is meant to be connected to the APM. I hope that solves your problem.

sorry, i got confused.

the gps is conencted to apm correctly, what is weird, is that the red light should be fixed and solid when the blue light of the gps is solid.

well that s not the case, it keep flashing, it only turn solid when i connect my quad to the mission planner

i am trying to find a solution to this issue here

The red LED indicates full 3D fix, which is a more rigorous test than the blue LED on the module itself. I don't understand why connecting to the Mission Planner should make a difference. What version of the ArduCopter and Mission Planner code are you using?

Herve: I think that GPS test is disabled at the moment (sorry; we'll reenable it in the next version), so what you're seeing is normal. But are you still getting no red LED, even when you have GPS lock (blue LED)?

PS: it's working properly in the ArduPlane code, so if you want to test your GPS you can always just load that temporarily.

Good loiter depends a lot on your frame and tuning. We're working on improving the algorithm so that it works better on all frames, but for now I suggest you try some of the techniques here (bottom) and here.

hi chris,

thx for the link now i have some clues for some testing.

there is something with wich i have difficulties in that kind of doc, there are no scale.

for example take a setting 4.000 . when i see that, to me, because there are 3 "0" after the coma, it mean that there is a difference between 000 and 001. but what is the max and the lowest? 

if default is 4.5 and i change it to 4.550, how do i know if it s a major change or we are talking cents out of a billion dollar bill ?

maybe you should try to implement some ruler or slider in the apm.

i am facing numbers, but i have no idea what is too big value or change, or step.

how can i be sure the step i use for find the right setting is on the good scale?

thxx for your time, and sorry for my english, i hope you understoud me

best regards
